selenium simple test says xpath is not a legal expression - xpath

I started using SST (selenium simple test) but ran into a problem when executing what seems to be a valid xpath expression '//div[div#data-type="folder-name"]'. SST fails with the following traceback:
Traceback (most recent call last):
File "/usr/local/lib/python2.7/dist-packages/sst/cases.py", line 207, in run_test_script exec self.code in self.context

The SST code line is:
names = get_elements_by_xpath('//div[div#data-type="folder-name"]')
If I run the same xpath statement using selenium (from python), not SST, it is a valid expression and returns the matching elements if there were any.
The pure selenium code line (where br is the firefox webdriver object) is:
elems = br.find_elements_by_xpath("//div[div/#data-type='folder-name']")
I understand this is a bit in the weeds, so if anyone has some hints as to how to debug the .js code that selenium creates in the /tmp directory that would be a big help.

It's not a valid XPath expression. This
//div[div#data-type="folder-name"]
Should probably read
//div[div/#data-type="folder-name"]
which is indeed what you have in one of your examples.

If you are trying to get all possible div tags with data-type="folder-name",
//div[#data-type="folder-name"]
If only children of the first div with data-type="folder-name",
//div[div/#data-type="folder-name"]

You don't show any markup, up i assuming you have
<div><div data-type="folder-name"></div></div>
you need:
elems = br.find_elements_by_xpath("//div//div[#data-type='folder-name']")

ADSError 857212673: Can't read variable values through name (pyads)

I've been having a problem lately where I can't access the value of any variable through their name. It's not a connection problem since I can read the value from the read() function just fine. However whenever I use the read_by_name function there's always the same error pyads.pyads_ex.ADSError: ADSError: Unknown Error (857212673).
Because it's an unknown error I haven't been able to find documentation on it. I'm using a BC9120 as a PLC and TwinCat 2. Does anyone know what might be causing this?
Code:
if self.plc.is_open == False:
self.plc.open()
print(self.plc.read(pyads.INDEXGROUP_MEMORYBIT, 0*8 + 0, pyads.PLCTYPE_BOOL))
print(self.plc.read_by_name("Test.M0", pyads.PLCTYPE_BOOL))

How could I resolve xmlrpc.client.Fault while trying to search a package through pip3? [duplicate]

The picture is an error when I pip search. Can you tell me how to fix it?

The pip search command queries PyPI's servers, and PyPI's maintainers have explained that the API endpoint that the pip search command queries is very resource intensive and too expensive for them to always keep open to the public. Consequently they sometimes throttle access and are actually planning to remove it completely soon.
See this GitHub issues thread ...
The solution I am using for now is to pip install pip-search (a utility created by GitHub user #victorgarric).
So, instead of 'pip search', I use pip_search. Definitely beats searching PyPI via a web browser
Follow the suggestion from JRK at the discussion at github (last comment) the search command is temporarily disabled, use your browser to search for packages meanwhile:
Check the thread on github and give him a thumb up ;)
search on website, https://pypi.org/,
then install the package you wanted
The error says
Please use the Simple or JSON API instead
You can try pypi-simple to query the pip repository
https://pypi.org/project/pypi-simple/
It gives an example too, I tried to use it here:
pypi-simple version 0.8.0 DistributionPackage' object has no attribute 'get_digest':
!/usr/bin/env python3

terraform plan is giving the error : function call (function yamldecode)

Please find the GitLab repo for the terraform scripts which we are using.
enter link description here
Run in terraform plan gives the below error in an all-in-one.YAML file for the elastic search.
Error: Error in function call
on kubernetes.tf line 49, in locals:

content after value.
enter image description here
As is describe in the fine manual:
Only one YAML document is permitted. If multiple documents are present in the given string then this function will return an error.
and one can trivially reproduce your error message:
content = yamldecode("---\nhello: world\n---\ntoo: bad\n")
on main.tf line 14, in resource "local_file" "example":

How to get function names of Linux Kernel files with pycparser?

I created fake header files under pycparser/utils/fake_libc_include for every header found in kernel/sched/core.c and put
#include "_fake_defines.h"
#include "_fake_typedefs.h"
into them. A few other header files where missing, lot's of headers from kernel/sched/sched.h for example. So I added them too.
Preprocessed the whole stuff with
gcc -nostdinc -E -Ipycparser/utils/fake_libc_include ../kernel/sched/core.c > core_pp.c
which gave no error.
So I tried to get the function names
python3 examples/func_defs.py core_pp.c
but it gives me the error:
Traceback (most recent call last):
File "examples/func_defs.py", line 46, in <module>

raise ParseError("%s: %s" % (coord, msg))
pycparser.plyparser.ParseError: ../kernel/sched/cpupri.h:14:2: before: atomic_t
What am I doing wrong? I've tried the redis example from this blog entry and it worked.
Adding the headers is just one part of the solution - this helps the preprocessor resolve the #include statements.
The other part of the solution is adding types that the parser would expect to find there to _fake_typedefs. This way pycparser will know the identified is a type and will be able to parse the code properly.

Accessing portal_registry via plone.app.theming

I'm trying to use a parameter expression in the plone.app.theming theming-controlpanel that gets a value from the portal_registry to use within the rules.xml file of the theme.
The goal is that if a boolean is set in the registry, the theme can allow/disallow certain content.
So my parameter expression (in theming-controlpanel) is
enable_ad_tags = python:context.portal_registry['lw.portal.enableadtags']
There is a corresponding boolean field in the portal_registry.
The rules.xml file has this rule:
<!-- Global Ad Tags -->
<drop css:theme="#globalAdTags" if="not($enable_ad_tags)" />
The problem is that on my local machine i get this error in the console all the time:

AttributeError: 'DirectoryResource' object has no attribute 'portal_registry'
Is there a problem with the pattern I am trying to use here?
Is there a better/safer way to achieve this?
Using portal instead of context works:
enable_ad_tags = python:portal.portal_registry['lw.portal.enableadtags']
IMHO context should also work, or context does not behave like it does, or the naming is wrong.
